Con's interactivity benchmark looks quite promising for finding
scheduler related interactivity regressions. It certainly has confirmed
what we already knew re: SCHED_FIFO performance, if we extend that to
SCHED_OTHER which is a more interesting problem then there's serious
potential for improvement. AFAIK no one has posted any 2.4 vs 2.6
interbench results yet...

I suspect a lot of the boot time issue is due to userspace. But, it
should be trivial to benchmark this one, just use the TSC or whatever to
measure the time from first kernel entry to execing init().
